filehdr – Self-descriptions in file headers

Func­tions for GNU Emacs Lisp to add “stan­dard”
file head­ers to a file. Th­ese head­ers con­tain ev­ery­thing you
might want to about a pack­age (and a lot you prob­a­bly
wouldn’t), ex­cept that they don't hold any in­for­ma­tion
about dis­tri­bu­tion or li­cens­ing.
